SPECIFICATION forming part of Letters Patent No. 434,747, dated August 19, 1890.

Application filed Juno 5, 1890l Serial No. 354,410. (No model.)

.To all whom it may concern:

Be it known that I, BENJAMIN F. ZELL, a citizen of the United States, and a resident of Orrville, county of Wayne, State of Ohio, have invented a new anduseful Improvement in Cultivators, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification.

My invention relates toA improvements in cultivators, and more particularly to that class of cultivators designated as riding or sulky cultivators, the object of which is to provide a strong and rigid support for the operator, to which all of the operative parts areadjustably secured within reach of the operator.

With these ends in view my invention consists in certain features of construction and combination of parts, as will be hereinafter described, and pointed out in the claims.

Figure l of the accompanying drawings is a view in perspective of acultivator illustrating my invention. Eig. 2 is a side view of a portion of detail.

Similar letters of reference indicate correspondin g parts in both the figures of the drawings.

A represents an inverted-U-shaped axleframe; B, a bifurcated pole, the rear end of which is secured to the main axle; C, an inverted-U-shaped front frame piece, which serves as asupport for the pole B and gang frame or beam D, the side bars E connecting the main axle with the frame-piece C. The axle-spindle E has a pivotal connection With axle frame, as shown at a, the axis of said pivot being vertical. On the inner end of said spindle is provided a toothed segment a', engaging a pinion a?, having corresponding teeth. Said pinion is mounted on the lower end portion of a vertical shaft 0.3. On the upper end portion of said shaft is provided an outwardly-projected arm a4. seen, these parts are used in duplicate. The arms a4 are pivotally secured together by a coupling-link a5.

At the top of the axle-frame A is provided a toothed quadrant a6, to which is pivotally secured a hand lock-lever am, one end of which As will beis pivoted to the link a5, as shown at al. The i .To adjust the front end of the gang-frame on the frame O,a number of short sleeves, as b', are provided, which may be placed 0n either side of the clip in such numbers or divisions as to place the clip in the desired line of lead -for the gang.

To raise or Alower the gang-frame or to lock it at any desired elevation, a quadrant b2 is secured to the axle-frame, to which is pivotally secured a lock-lever b3, having one of its ends connected by a lifting-rod b4 to the gangframe D.

The gang frame or beam D is formed of a continuous bar extending from the framepiece C to the rear portion of the wheels H,

said bar being bent in a zigzag form to properly place the plows-that is, bent from alignment from z to y, from y to kfrom m to w, and from w to fn, to which the plow-standards are secured in the usual way, abrace or girder portion u extending from to z.

` The plows are secured to the standards o by an open clip b5, through the lips of which is passed a tightening-bolt b. By slacking the bolt the clip may be moved up or down on the standard and secured in desired adjustment by tightening said bolt, or turned obliquely to the line of draft. The blade t7 may be secured to the clip by rivets or screws.

On the rods b4 a distance from the lower end is provided a collar b, below which is placed a coil-spring b9, the lower end of which rests on a perforated plate d, secured to the gang-frame. The spring serving as a cushion to all of the plows, in the event of a`plow striking an obstruction the spring willryield tothe pressure, the lower end of the rod b4 passing down through the plate d and between the bars forming the gang-frame.

To secure the corn-shield J to the gang- IOO frame, a spring-carrier L is provided, having one of its ends d secured to the frame,acoil d2 at its central portion, and its free end d3 secured to the shield, by which arrangement the shield may rise and fall independently of the frame D.

In operation the driver is seated on the seat K, his feet resting on the supportsA d, to raise or lower the gang-frame and plows, and to fix them in desired adjustment he will move the hand-lever b3 about its pivotal connection with the quadrant b2, the locking-bolt to engage the teeth at the desired point, and to turn the wheels H to travel obliquely to\ the line of draft for the purpose of holding the plows to the corn on hillsides, or to keepI the machine from sliding bodily down when used on sloping ground,thelock-levera10 is moved about at its pivotal connection with the quadrant a, the link 0.5, with the arms a4, vibrated, rotating the shafts a3 and pinions a2, said pinions engaging the segment a', by which movement the spindle F is Vibrated about its pivotal connection a with the frame A.

The convenience and ease with which the several parts may be operated to adapt them to the condition of the ground vand the crop to be cultivated will be apparent to all persons familiar with the use of such machines.

Having thus fully explained the nature and object of my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination, in a cultivator, of the invertcd-U-shaped axle-frame A, the divided tongue B, the invertcd-Ushaped frame-piece 4shaft a3, journaled to said axle-frame, and

having at their upper ends arms a4,pivotally secured together bya link a5, a toothed quad-V rant a6, and an actuating lock-lever-b3, by which the spindles maybe rotated about their pivotal connection with the axle-frame to turn the carrying-wheel H obliquely to the line of draft, substantially as described, and for the purpose set forth. l

2. The combination of the inverted U- shaped axle-frame, the spindles F, pivotally secured thereto, and the described meansfor rotatingsaid spindles about their 'pivotal counection with said frame, the segment 192,10cklever b3, lifting-rod b4, spring b9, and gan;N frame D, substantially as described, and the Vpurpose set forth.

3. The combination, with a cultivator as hereinbefore described, of a gang-frame of the form substantially as herein shown and described, standards o, secured thereto, blades 197, secu red to said standards by the open clips b5, the clip b, and the sleeves b', substantially as described, and for the purpose set forth.

.In testimony whereof I have hereunto set my hand this 31st day of May, A. D. 1890.
